Could they become a new fresh water plague?

Not that I would suggest tampering with an ecosystem, but Zebra Mussels
are not without some positive aspects. Their filtering capabilities can
improve water quality and clarity. There are reports of areas where the
smallmouth, perch, and even salmon fishing has improved after Zebra
Mussel infestations.

What eats them? So many acres of sunlit water will produce x tons of
plants which will support y tons of animals. It is looking like, some
places, all the animals will be mussels, and no fish whatever.
